IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 49,408, dated August15, 1865.

To all whom et may concern:

Be it known that I, WILLIAM D. HOOKER, of Stockton, in the county of SanJoaquin and State otl California, have invented a new and useful Improvemnt in DoubleActin g Suction and Force Pumps for Raising andForcing Water or other Liquids; and I do hereby declare that thefollowing is a full, clear, and exact description ofthe construction andopera-tion of the same, reference being had to the annexed drawings,making a part of' this speciiication, in Which- Figuie 1 is alongitudinal secion,` showing -the arrangement of the valves, suctionand discharge chambers y y. Fig. 2 is also a longitudinal section, m wshowing the line ot' section. Fig. 3 is a perspective view ot` valve.

Similar letters of reference indicate corre sponding parts in the threefigures.

The nature of my invention consists inseparating the suction anddischarge chambers and suction and discharge valves by a partition, saidpartition forming a chamber in which the valves operate, and fromwhichthey can be readily removed, the chamber also acting as a guide tokeep the valves in position, as will be `hereinafter more fully shotvnund described.

To enable others skilled in the art to fully understand and construct mymachine, I will proceed to describe it.

a represents the pu nip-barrel, constructed of metal and of cylindricalform b b, thepump piston; c, the packing, made ot' metal, india-`rubber, or any material commonly used for such purpose; d, thepump-barrel head; c, the piston-rod; j', the handle; g, the arm on whichthe handle rotates; It, the vertical and inclided partition separati ngthe suction-cham her and suction-valves from the dischargechamber anddischarge-valves d a2, the suction-valves; b b2, the discharge-valves,said valves heilig made of metal and fitted to the valve-seats, orcovered with leather or india- I'uober or any substanceusually usedforsuch purpose, said covering being secured to the valves by means ot'a screw and Washer, as shown; c c2, the suction-valve seats; d cl2, thedischarge-valve seats; t', the induction port; j, the eduction-port; la,the air-chant ber; Z, discharge-spout; m m m m, apertures through whichbolts or screws are inserted to secu rethe chamber to pum p-cylinder orWhere the chamber is east with the cylinder I leave an aperture oropening (indicated by dotted lines it n n a) opposite the valves,through which the valves can bereadilyremoved,said aperture a beingcovered by a cap or plate and secured to the chamber `in the same manneras A the chamber described is secured to the pumpcylinder; o, thesuction-chamber; p, the discharge-chamber; r, the ports in thepumpbarrel. As the pistonbis drawn up thepumpbarrel a the vacuum createdthereby causes the suction-valve a' to open, and the water is drawn intothe cylinder through the induetion-port i. When the piston b descendsthe suction-valve a. is closed, discharge-valve b' is opened, and thewater is forced `out into the. discharge-chamber p and out of spout Z.At y the same time that the piston is descending the vacuum createdabove the piston thereb t l causes the suction-valve a2 to open, andWater is drawn up the suetiolrchamber o through or under thesuction-valve a2 i the cylinder, to be forced outvthrough dicharge-valve b2 into the discharge'chambei and out at the spout L on thereturn or ne" upward stroke of the piston b, thereby eau ing acontinuous stream to flow from the di charge-spout Z.

vThe vertical inclined partition 7L is so ranged as to divide thesuction-chambe from the discharge-chamber p, and is c nected or cast tothe valve-seats c' c2 d d2 suoli a manner as to form a chamberiuwh thevalves lay entirely independentyof `1th chamber, said chamberae'ting"asi al guide the valves in their upward movenm-.nts.y` (Seej Fig. 2.) l

What l claim as my improve to secure by L etters Patent, y p l i 1 Thevertical inclined partitioirh.;illrcombizna. tion with thesuction-valveseats dotanddischarge-valve seats d dltghed holearranged asdescribed, and forlthefpurposespecitied.
